    OUTLINE § 1 In order to transmit the measurement data with ARK-710A to an external computer, ARK-710A is provided with RS-232C interface as the standard function. This manual provides the way to receive the measurement data from ARK-710A utilizing this interface.

  • Page 7: Transmission Sequence

    TRANSMISSION SEQUENCE § 2 Two kinds of the transmission sequences, “NIDEK” and “NCP10”, can be selected by setup of the “I/F Mode” of the parameter. Communication sequence NIDEK NCP10 DTR/DSR control RS/SD command control Data transmission Available by the demand from a PC available Checksum data A setup of "NIDEK"...

  • Page 8: In The Case Of "Ncp10

    CL command 2.2 In the case of “NCP10” DTR/DSR control is not performed. DTR signal of the ARK-710A is always low on the circuit. DTR signal of the external computer side does not affect the transmission in either condition. Moreover since RS/SD command control is not performed, pressing the print button sends the data directly.
